Description

Technical Field

[0001] This utility model relates to electrical structures, specifically to a pulsator washing machine equipped with an inner drum clutch structure. Background Technology

[0002] Top-loading washing machines achieve both synchronous operation of the inner tub and the pulsator, as well as independent operation of the pulsator, primarily through a mechanical gear clutch structure. However, in practical applications, when the pulsator operates independently, the high-speed rotating water flow generates inertia, and the movement of the clothes with the water flow also creates inertia. These two inertias can easily cause the inner tub to rotate, affecting washing uniformity and potentially increasing energy consumption. To solve this problem, the industry commonly uses a mechanical clutch brake lock-up structure, which forcibly locks the inner tub to suppress rotation. However, this structure requires multiple sets of gears, brake pads, and transmission rods, resulting in a complex overall structure, high requirements for machining precision and assembly processes, high manufacturing costs, and inconvenient maintenance.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model discloses a pulsator washing machine equipped with an inner drum clutch structure.

[0005] The technical solution adopted in this embodiment of the utility model is as follows: A pulsator washing machine equipped with an inner drum clutch structure includes: an outer drum with a protruding first limiting member on its inner bottom surface; an inner drum installed in the outer drum with a limiting hole at its bottom; an outer float installed between the outer drum and the inner drum, the outer float including a second limiting member sleeved on the first limiting member and slidable relative to the first limiting member within the height range of the first limiting member; and a pulsator installed in the inner drum. When the outer float is buoyed up, the second limiting member moves upward to insert into the limiting hole, fixing the position of the inner drum; when the outer float falls under gravity, the second limiting member moves downward to disengage from the limiting hole, allowing the inner drum to rotate with the pulsator assembly.

[0006] A further technical solution is that the second limiting member includes a protruding structure integrally formed with the upper surface of the outer float, or the protruding structure of the second limiting member is made of a soft material, or is wrapped with a soft material, installed on the outer float and protruding from the upper surface of the outer float.

[0007] A further technical solution is that the washing machine further includes a power assembly; the impeller is fixed to the power output shaft of the power assembly via a handle assembly.

[0008] A further technical solution is that the handle assembly includes a mounting position located at the center and a plurality of reinforcing holes arranged radially along the mounting position; a spline hole is provided at the center of the impeller; the power output shaft passes through the spline hole and mates with the spline hole; the spring plunger screw passes through the reinforcing hole and presses against the positioning groove opened at the upper end of the power output shaft, thereby fixing the power output shaft axially.

[0009] A further technical solution is that the handle assembly includes a first fixed position opened in the circumferential direction; the impeller includes a second fixed position opened in the circumferential direction; the handle assembly is fixed together with the impeller assembly through the first fixed position and the second fixed position.

[0010] A further technical solution is that the washing machine further includes an inner float and a turntable fixed to the inner drum; the inner float is torque-transmittable and fixed to the impeller, and can move coaxially relative to the impeller; the inner float moves downward to lock the turntable, causing the impeller to drive the inner drum to rotate, or the inner float moves upward to disengage from the turntable, so that the inner drum remains stationary when the impeller rotates.

[0011] A further technical solution is that a plurality of mating grooves are circumferentially provided on the impeller; mating parts corresponding to the mating grooves are provided on the inner float in a uniform number and position; the mating parts are inserted into the mating grooves, and the inner float can move axially relative to the impeller within the height range of the mating parts.

[0012] A further technical solution is that the turntable includes a plurality of upwardly protruding blocking members arranged in a ring; each blocking member has a first working surface, which includes a radially arranged vertical surface perpendicular to the surface of the turntable and an inclined surface at an obtuse angle to the surface of the turntable; the inner float includes a plurality of engaging members that interfere with the blocking members in the circumferential direction; each engaging member includes a second working surface that cooperates with the first working surface, which includes a radially arranged guide surface and a driving surface; when the inner float moves upward under the action of buoyancy, when the impeller rotates, the guide surface contacts the inclined surface and slides upward along the inclined surface until the engaging member slides past the surface of the blocking member, and the turntable remains stationary; when the inner float moves downward under the action of gravity, when the impeller rotates, the driving surface abuts against the vertical surface, causing the turntable to rotate synchronously.

[0013] A further technical solution is that the vertical plane and the driving surface are both perpendicular to the rotation plane of the inner float, and the vertical plane and the driving surface are parallel to each other and parallel to the radial direction of the rotation plane of the inner float.

[0014] A further technical solution is that the blocking member has a first working surface on both sides, and the inclined surface and the vertical surface are in opposite positions on both sides of the blocking member; the engaging member has a second working surface on both sides, and the guiding surface and the driving surface of the second working surface are both configured to cooperate with the first working surface opposite to the second working surface.

[0015] The beneficial effects of this utility model embodiment are as follows: This utility model embodiment achieves the switching of the inner tub's limiting working state by setting an external float between the outer tub and the inner tub, utilizing the effects of buoyancy and gravity: during washing, when there is water in the outer tub, the external float floats due to buoyancy, and its second limiting member inserts into the limiting hole of the inner tub, locking the position of the inner tub. Under the inertia of the water flow driven by the impeller and the inertia of the clothes' movement, the inner tub is prevented from rotating. The structure of this utility model embodiment can achieve the limiting function through the simple cooperation of the float and the limiting hole, without the need for other complex mechanical structures such as brakes. The structure is simple, ensuring the stability of the water flow pattern during washing, improving washing uniformity and reducing clothes tangling.

[0016] In this embodiment of the utility model, a dual limiting structure is further proposed, in which the inner float and the outer float cooperate. During washing, the inner float rises and disengages from the turntable, and the outer float limits the inner drum to ensure that the inner drum does not rotate with it. During spin-drying, the inner float falls and locks the turntable, and the outer float releases the inner drum to ensure that the inner drum rotates synchronously with the impeller, thereby further reducing the sway and noise during operation and improving the reliability of switching between operating conditions.

[0017] In this embodiment of the utility model, the blocking member is provided with a first working surface on both sides, and the meshing member is provided with a corresponding second working surface on both sides. The symmetrical reverse design of the first and second working surfaces can adapt to the working conditions of the impeller rotating in both directions. Regardless of whether the impeller rotates clockwise or counterclockwise, it can achieve smooth avoidance or torque transmission, thereby improving the versatility and smoothness of product operation.

[0029] This embodiment discloses a pulsator washing machine equipped with an inner drum clutch structure. Figure 1This is an exploded view of a portion of the structure of the washing machine in an embodiment of this utility model. For example... Figure 1 As shown, the washing machine includes an outer drum 1, an inner drum 2, an outer float 3, and a pulsator assembly. The inner drum 2 is installed inside the outer drum 1. In this embodiment, the outer drum 1 has two inner drum mounting positions, allowing two inner drums 2 to be installed simultaneously. Only one inner drum 2 and other related structures are shown in the figure. Of course, this embodiment can also be applied to implementations where the outer drum 1 has only one inner drum mounting position, or two or more inner drum mounting positions.

[0030] Figure 2 This is a schematic diagram of the outer cylinder in an embodiment of this utility model. Figure 2 As shown, a first limiting member 101 protruding towards the inside of the outer cylinder 1 is provided on the inner bottom surface of the outer cylinder 1. A drain hole 102 is also provided at the bottom of the outer cylinder 1, which is the lowest point at the bottom of the outer cylinder 1 and is used for drainage. Figure 3 This is a schematic diagram of the inner cylinder in an embodiment of the present utility model, as shown below. Figure 3 As shown, a limiting hole 201 is formed at the bottom of the inner drum 2. An outer float 3 is installed between the inner bottom surface of the outer drum 1 and the outer bottom surface of the inner drum 2. The outer float 3 includes a second limiting member 301 that is sleeved on the first limiting member 101 and can move axially relative to the first limiting member 101 within the height range of the first limiting member 101. The impeller assembly is installed in the inner drum 2 and can be driven to rotate by the power output shaft 501 of the power assembly 5. The power assembly 5 is driven by a motor. The specific structure of the motor and the power assembly 5 is a conventional structure in impeller washing machines and is not an innovation of this utility model, so it will not be described in detail. The impeller assembly includes an impeller 4 and a handle assembly 6 that fixes the impeller 4 to the power output shaft 501.

[0031] When the outer cylinder 1 is filled with water, and the buoyancy of the outer float 3 is greater than its weight, that is, when the outer float 3 floats up due to buoyancy, the outer float 3 moves upward and closer to the inner cylinder 2. The second limiting member 301 is inserted into the limiting hole 201. At this time, the lower part of the second limiting member 301 is still fitted on the first limiting member 101, and the position of the inner cylinder 2 is fixed. At this time, the impeller assembly rotates, and the inner cylinder 2 remains stationary. When the water in the outer cylinder 1 is discharged, and the weight of the outer float 3 is greater than its buoyancy, that is, when the outer float 3 falls due to gravity, the outer float 3 moves away from the inner cylinder 2. The second limiting member 301 moves downward until it is disengaged from the limiting hole 201. The inner cylinder 2 is unrestricted and can rotate with the impeller assembly.

[0032] This embodiment uses a floating outer float 3 between the outer tub 1 and the inner tub 2. When the washing machine is in washing mode, the inner tub 2 contains water, and the outer float 3 floats up and engages with the limiting hole 201 of the inner tub 2 to limit its position. This prevents the inner tub 2 from rotating with the water flow and the inertia of the clothes caused by the operation of the impeller assembly, resulting in a more stable water flow, more even washing, and reduced tangling and knotting of clothes. After the washing machine drains, the outer float 3 falls and automatically releases the inner tub 2, allowing it to rotate during spin-drying. Throughout the entire process, the state of the inner tub 2 does not require manual switching but can automatically switch according to the washing machine's operating conditions. Moreover, this process is triggered only by the relationship between buoyancy and gravity, eliminating the need for additional motors, solenoid valves, or other driving components, thus simplifying the overall structure of the washing machine.

[0033] Figure 4 This is a schematic diagram of another embodiment of the external float in this utility model. Figure 1 This illustration shows one embodiment of the external float 3. Figure 1 In the middle, the second limiting member 301 includes a protruding structure integrally formed with the upper surface of the outer float 3, and the back of the second limiting member 301 is a groove, which is fitted onto the first limiting member 101. Figure 4 This illustrates another implementation of the external float 3, in Figure 4 In this embodiment, the protruding structure of the second limiting member 301 is made of a soft material, or its exterior is wrapped with a soft material. It is installed on the outer float 3 and protrudes from the upper surface of the outer float 3. The mounting support of the second limiting member 301 also has a groove for fitting onto the first limiting member 101. In this embodiment, the outer float 3 has multiple mounting holes at its mounting position, and the second limiting member 301 has corresponding multiple mounting rods for inserting into the mounting holes and fixing the second limiting member 301, forming a protruding structure for cooperating with the limiting hole 201 of the inner cylinder 2 to limit the movement of the inner cylinder 2. Figure 4 In this implementation method, soft materials can prevent contact noises caused by impacts and collisions, making the washing machine run more quietly.

[0034] Figure 5 This is an exploded view of the impeller assembly in an embodiment of this utility model. Figure 6 for Figure 5 A diagram showing another direction. (See example.) Figure 5 , Figure 6As shown, the handle assembly 6 includes a mounting position 601 located at the center and a first fixing position 602 surrounding the mounting position 601. The impeller 4 includes a splined hole 401 located at the center and a second fixing position 402 surrounding the splined hole 401. The power output shaft 501 passes through the splined hole 401 and engages with the spline of the splined hole 401, so that the rotation of the power output shaft 501 can drive the impeller 4 to rotate. Using fasteners such as screws, the handle assembly 6 and the impeller 4 are fixed together through the first fixing position 602 and the second fixing position 402. A plurality of reinforcing holes are evenly and symmetrically arranged radially along the mounting position 601, and a positioning groove is formed at the upper end of the power output shaft 501. The power output shaft 501 extends into the mounting position 601 after passing through the splined hole 401. The spring plunger screw 603 passes through the reinforcing hole and presses against the positioning groove, fixing the power output shaft 501 axially. The power assembly 5 and the impeller 4 transmit power via a spline connection, ensuring stable torque transmission and high efficiency. Axial positioning is achieved using a spring plunger screw 603, resulting in a simple and reliable locking structure.

[0035] Furthermore, this embodiment also discloses a mating structure between the impeller 4 and the inner drum 2. Specifically, the washing machine also includes an inner float 7 and a turntable 8 fixed to the inner drum 2. The inner float 7 is torque-transmittablely fixed to the impeller 4 and can move up and down coaxially relative to the impeller 4. Specifically, the impeller 4 has a plurality of mating grooves 403 circumferentially. The inner float 7 is provided with mating parts 701, the number and position of which correspond to the mating grooves 403. The mating parts 701 are inserted into the mating grooves 403, and within the height range of the mating parts 701, the inner float 7 can move axially relative to the impeller 4. When the impeller 4 rotates, it can drive the inner float 7 to rotate.

[0036] When there is no water in the inner drum 2, the inner float 7 moves downwards due to gravity until it locks onto the turntable 8, causing the pulsator 4 to rotate the inner drum 2. Alternatively, when there is water in the inner drum 2, the inner float 7 moves upwards due to buoyancy until it disengages from the turntable 8, causing the pulsator 4 to rotate while the inner drum 2 remains stationary. The interaction between the pulsator 4 and the inner drum 2 requires no additional power and can automatically switch according to the washing machine's operating conditions. It requires no motors, solenoid valves, or other driving components, resulting in high reliability. Due to the absence of other mechanical structures, the probability of failure is low, and the control logic is simple.

[0037] Furthermore, the inner float 7 and the outer float 3 can work together during operation. During washing, both the outer tub 1 and the inner tub 2 are filled with water. The outer float 3 limits the inner tub 2, and the inner float 7 disengages from the turntable 8 on the inner tub 2. This dual structure ensures that the inner tub 2 does not rotate with the outer float. During spin-drying, both the outer tub 1 and the inner tub 2 are empty of water. The outer float 3 disengages from limiting the inner tub 2, and the inner float 7 engages the turntable 8. This dual structure ensures that the inner tub 2 rotates stably with the impeller 4, reducing movement and noise during operation.

[0038] Figure 7This is an exploded view of the turntable and inner float in an embodiment of this utility model. Figure 8 for Figure 7 Another diagram from which to view it. (As shown) Figure 7 , Figure 8 As shown, the turntable 8 includes a plurality of upwardly protruding blocking members 801 arranged in a ring. Each blocking member 801 has a first working surface, comprising a radially arranged vertical surface 8011 perpendicular to the surface of the turntable 8 and an inclined surface 8012 at an obtuse angle to the surface of the turntable 8. The inclined direction of the inclined surface 8012 is approximately along the circumference of the turntable 8, i.e., in the direction of rotation of the turntable 8 or the opposite direction of rotation, extending from the bottom to the top of the inclined surface 8012. The inner float 7 includes a plurality of engaging members 702 that interfere with the blocking members 801 in the circumferential direction. The number of engaging members 702 is the same as that of the blocking members 801. Each engaging member 702 includes a second working surface that mates with the first working surface, comprising a radially arranged guide surface 7022 and a drive surface 7021. Specifically, when the inner float 7 rotates coaxially with respect to the turntable 8, the guide surface 7022 and the inclined surface 8012 are opposite to each other and can interact with each other, and the driving surface 7021 and the vertical surface 8011 are opposite to each other and can interact with each other.

[0039] When the inner float 7 moves upwards away from the turntable 8 under the influence of buoyancy, the impeller 4 drives the inner float 7 to rotate. The guide surface 7022 contacts the inclined surface 8012 and slides along the inclined surface 8012, causing the engaging part 702 to slide along the upper surface of the blocking part 801. The two cannot transmit torque, and the turntable 8 remains stationary. The design of the inclined surface 8012 avoids rigid jamming between the engaging part 702 and the blocking part 801, allowing them to avoid interference. When the inner float 7 moves downwards to close to the turntable 8 under the influence of gravity, the engaging part 702 is close to the turntable and is in the corresponding circumferential position of the blocking part 801. When the impeller 4 drives the inner float 7 to rotate, the driving surface 7021 directly contacts the vertical surface 8011 of the blocking part, pressing against the vertical surface 8011. The vertical surface 8011 bears the torque, and the force of the driving surface 7021 is transmitted to the turntable 8 through the vertical surface 8011, causing the turntable 8 and the inner cylinder 2 to rotate synchronously.

[0040] Furthermore, both the vertical surface 8011 and the driving surface 7021 are perpendicular to the rotation plane of the inner float 7, and are parallel to each other and simultaneously parallel to the radial direction of the rotation plane of the inner float 7. The torque transmission direction is the rotation direction. This design structure allows the force to be directly transmitted along the rotation direction without directional offset. Moreover, the vertical surface 8011 and the driving surface 7021 are in surface contact, maximizing and uniformly distributing the force, resisting rotational slippage, preventing the generation of force components in other directions, and avoiding torque loss caused by localized wear, thus preventing energy waste.

[0041] Furthermore, both sides of the blocking member 801 have a first working surface, and on both sides of the blocking member 801, the inclined surface 8012 and the vertical surface 8011 are in opposite positions. In this embodiment, see... Figure 6 and Figure 7 Looking at the blocking member 801 alone, along the direction of rotation, on one side of the blocking member 801, the inclined surface 8012 is close to the rotation axis, and the vertical surface 8011 is away from the rotation axis. On the other side of the blocking member 801, the inclined surface 8012 is away from the rotation axis, and the vertical surface 8011 is close to the rotation axis. Meanwhile, both sides of the engaging member 702 have second working surfaces. The guide surface and drive surface of the second working surfaces are both configured to cooperate with the first working surface opposite to the second working surface. That is, when the engaging member 702 is close to the turntable and in the corresponding circumferential position of the blocking member 801, the engaging member 702 will have two second working surfaces, respectively opposite to the two adjacent blocking members 801. The method of setting the second working surfaces is that the guide surface 7022 is opposite to the inclined surface 8012, and the drive surface 7021 is opposite to the vertical surface 8011.

[0042] This structure is compatible with the bidirectional rotation of the impeller 4. During washing machine operation, the clothes need to be agitated in both directions. The opposing action surfaces on both sides can be matched to the forward and reverse rotation conditions respectively. Regardless of whether the impeller 4 rotates clockwise or counterclockwise, torque transmission is achieved through the corresponding drive surface and vertical surface, and the guide surface and inclined surface avoid each other, ensuring consistent and reliable bidirectional operation. Furthermore, torque transmission and avoidance actions during both forward and reverse rotation of the impeller 4 are achieved through a symmetrical structure, avoiding uneven wear caused by long-term stress on a single action surface, thus extending the service life of the blocking and meshing components. There is also no need to design different structures for blocking or meshing components for forward and reverse rotation; bidirectional adaptation is achieved through the opposite arrangement on both sides, reducing the types of parts and lowering the complexity of processing and assembly.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
